AI coding agents hit a product-side bottleneck in week four, CTO pilot reveals

An engineering lead at a hardware manufacturer (100+ engineers, codebase dating to 2017, planning a major rewrite next year with existing staff) found his AI adoption bottleneck arrived in week four of a pilot — not when ten teams were using AI, but with just two engineers. With agents writing code faster, his Scrum teams outran product-side capacity: "I don't have 10 product owners" to write specs and keep the agents fed.

The pilot: one self-contained mobile app, two of his engineers directing and reviewing agent-written work over four weeks. Bar to clear: production-quality, maintainable software without line-by-line inspection.

Key takeaway: when agents speed up engineering, the constraint often shifts to product/requirements staffing, not engineering headcount.
